When to roll initiative?

[DarkMaster]

Cinematically the Assasin starts drawing his dagger (which kicks off the combat round) and the guard are either slow enough that the Assasins attacks go in first or they are fast enough to get a blow or two in before the Assasin strikes. So the report would be "He went for his dagger and we had to kill him".

I agree 100%
